type "array" with "duplicate-arguments-array" works inconsistently

[juergba]

array of type number is not affected by duplicate-arguments-array and doesn't reduce duplicated arguments:

var args = parse(
    ['--file', '2', '--file', '6', '--timeout', '2s', '--timeout', '800'], {
        array: [{key: 'file', number: true}],
        string: ['timeout'],
        configuration: {
            'duplicate-arguments-array': false
        }
});
console.log(args);         // { _: [], file: [ 2, 6 ], timeout: '800' }

array of type string does reduce duplicated arguments with duplicate-arguments-array:

var args = parse(
    ['--file', '2', '--file', '6', '--timeout', '2s', '--timeout', '800'], {
        array: [{key: 'file', string: true}],
        string: ['timeout'],
        configuration: {
            'duplicate-arguments-array': false
        }
});
console.log(args);         // { _: [], file: [ '6' ], timeout: '800' }

An array of type boolean is always reduced, indepently of duplicate-arguments-array. So it doesn't seem possible to build an array of boolean with more than one element.

It is not clear:

• wether duplicate-arguments-array should reduce array's at all. Analysing the tests, the answer is yes. Maybe it would be more logical to exclude array's from this rule?
• the behavior of typed array's is not consistent (number <=> string).

With the current master this issue has been fixed:

var args = parse(
    '--nr 2 3 --nr 5 6 --str foo bar --str baz yop --bool true false --bool false true', {
        array: ['nr', 'str', 'bool'],
        number: ['nr'],
        string: ['str'],
        boolean: ['bool'],
        configuration: {
            'duplicate-arguments-array': false
        }
});

output:

{ _: [],
  nr: [ 5, 6 ],
  str: [ 'baz', 'yop' ],
  bool: [ false, true ] }

This issue can be closed.
